Canadiens sign defenseman Mike Matheson to five-year extension

Montreal had plenty of space to make it happen as well. Before Matheson’s extension, the Canadiens had approximately $26M in cap space for the 2026-27 campaign.

It was worth it for Montreal Canadiens to re-sign Mike Matheson

There’s little argument to claim he wasn’t worth retaining either. Toward the beginning of his career with the Florida Panthers and Pittsburgh Penguins, Matheson had scored 49 goals and 138 points in 417 games with a -9 rating, averaging 20:15 of ice time in a top-four role. That production pales in comparison to his time in Quebec.

The 31-year-old blue liner has already surpassed his previous production in nearly half as many seasons. Though he earned more ice time in the offensive zone before the emergence of Hutson and the acquisition of Dobson, Matheson has scored 29 goals and 141 points in 232 games donning the bleu, blanc et rouge.

Still, there is some cause for concern. At even strength, Matheson hasn’t garnered above a 90% on-ice save percentage at even strength since his first year with the Canadiens, though some of that can be attributed to beginning 56.7% of his shifts in the defensive zone. Similarly, according to MoneyPuck, Matheson hasn’t produced a percentage above 50% on-ice goals share at any point during his time with Montreal.

As they’ve done this season by placing him alongside Dobson, Matheson will likely transition into a complementary piece rather than being expected to carry his defensive pairing. Comparatively, Dobson has only had one season in which he’s averaged less than 50% on-ice goals share.

Regardless, the Canadiens now have their top-four defensemen signed through the 2030-31 season, and that’s without considering the expected emergence of top prospect David Reinbacher. Now, with their last important internal negotiation out of the way, Hughes and the rest of Montreal’s front office can focus entirely on bringing a second-line center into the mix.
